Thanks for the explanation, I wasn't aware of that!

Now where to get these kinds of replacement parts? I was looking around at aliexpress and I found the Mosfet. But do you guys have a general recommendation where to buy these kinds of parts? I do have a lot of donor boards and gpus to steal from, but I would like to avoid transplanting parts with only little life left in them. Any best practices?

btw. I tested the card with in a test computer with a thermal camera attached and It was really good visible that the area around the mosfet heated up very fast. I stopped...

Thank you two for the replies and the boardview! I was already giving up to find it since in another post about the exact same card nobody was able to share one.

[USER="531309"]speaktorob[/USER] So far I can say that all D1 phases are shorted with all S2 phases from the specsheet of mosfet Q32. from G1 to G2 there is a resistance of 2.7M Ohm. in comparison, the mosfet Q29 does not have any shorts so I think that one is healthy, the Q32 is done and needs to be replaced.

Nevertheless I wonder what to do with the pads of R174 and R172 since you both are of the...

Thank you for the tip! Yeah I mean the mosfet with the description 22CA N7CC (datasheet attached). But how can I apply voltage to the GPU with a desktop PSU in order to figure out if there are any more problems? Do you know whether there is a guide or something like this on this forum?
Thankful for any help or advice! ...

Thank you for your reply! I was about to find out whether the IC next to the two burnt resistors is also dead. Got me a thermal camera to see if there is anything happening on the board when I apply voltage, currently trying to figure out how I can make it visible.. any recommendations on the values for current and voltage when testing the gpu?

I also found this guy who basically only replaced one of the resistors also with a 0 Ohms resistor in order to have a fail safe option that can just burn through if anything else is failing again. [url]https://www.youtube.com/watch?v=yD7Ud...

I got myself a better camera by now and the needed tools to try my repair. I just wonder how I could figure out what value the blown transistors had. I attached some pictures of the pcb below....

Thank you for the reply!
Do you mean number C177?...

Hey guys,

This is Moe from Germany. I began working inside of computer approximately 5 years ago after I spent quite some time repairing smartphones (mostly apple products..). My actual job is being a cloud architect but I like the backbone of the cloud as well.
By now I've done a lot of troubleshooting faulty bioses, software and hardware incompatibility stuff but now I'm interested to try and fix the actual broken hardware parts such as Motherboards and GPU's since they kinda stockpiled over the last years.

Im really looking forward to learn more about the topic...

Did you happen to solve the problem with the Mosfet? And were you also able to find a proper schematics for the card?
I have one here with two blown fuses and I wonder which ones I need to replace it.
